Support variables as Map keys in expressions and patterns

Erlang will accept any expression as keys in Map expressions and it will accept literals or bound variables as keys in Map patterns.

Make sure to install .hrl files when needed

Invoking debugger functions ia/1 and iaa/1 crashed, when it tried to invoke the old and removed gs based gui functions.

Fix evaluation of map updates in the debugger and erl_eval

Reported-by: José Valim

Own Id: OTP-11922

The debugger now correctly evaluates code such as 'X = true andalso X'. (Thanks to Anthony Ramine.)

Own Id: OTP-11553

A few subtle bugs in the evaluation of code in the debugger has been corrected. (Thanks to Anthony Ramine.)

Own Id: OTP-11676

Application upgrade (appup) files are corrected for the following applications:

asn1, common_test, compiler, crypto, debugger, dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe, inets, observer, odbc, os_mon, otp_mibs, parsetools, percept, public_key, reltool, runtime_tools, ssh, syntax_tools, test_server, tools, typer, webtool, wx, xmerl

A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.

(Thanks to Tobias Schlager)

Own Id: OTP-11744

Removed gs based applications and gs based backends. The observer application replaces the removed applications.

*** POTENTIAL INCOMPATIBILITY ***

Support Maps syntax in debugger (Thanks to Anthony Ramine).

Own Id: OTP-11673

Fix matching of floating point middle-endian machines. Thanks to Johannes Weissl.

Own Id: OTP-11201

A new checkbox has been added. When it is checked, the range set by the erl flag +pc is used for determining when to print lists of integers as strings. When it is unchecked, integer lists are never printed as strings.

A minor incompatibility: settings saved by Erlang R16B01 or later cannot be read by Erlang R16B or earlier.

Own Id: OTP-10899

Erlang source files with non-ASCII characters are now encoded in UTF-8 (instead of latin1).

Own Id: OTP-11041 Aux Id: OTP-10907

The +pc flag to erl can be used to set the range of characters considered printable. This affects how the shell and io:format("~tp",...) functionality does heuristic string detection. More can be read in STDLIB users guide.

Fix Debugger settings dialog due to changed behavior in wxFileDialog (Thanks to Håkan Mattsson)

Own Id: OTP-10621

Support for Unicode has been implemented.

Own Id: OTP-10302

Where necessary a comment stating encoding has been added to Erlang files. The comment is meant to be removed in Erlang/OTP R17B when UTF-8 becomes the default encoding.

Own Id: OTP-10630

Integer lists and utf-8 binaries in variables are now displayed as strings.

Own Id: OTP-10679

Fixed disappearing breakpoints bug, reported by Ricardo Catalinas Jiménez.

Own Id: OTP-9950

Fix "OK" spelling in debugger messages and variables

Simple code refactor in the debugger: renames all the occurrences of "Ok" to "OK" in the code, variable names and strings. This improves the consistency of the code and follows the GTK UI where "OK" is always used.(Thanks to Ricardo Catalinas Jiménez)

Variables are now now allowed in 'fun M:F/A' as suggested by Richard O'Keefe in EEP-23.

The representation of 'fun M:F/A' in the abstract format has been changed in an incompatible way. Tools that directly read or manipulate the abstract format (such as parse transforms) may need to be updated. The compiler can handle both the new and the old format (i.e. extracting the abstract format from a pre-R15 BEAM file and compiling it using compile:forms/1,2 will work). The syntax_tools application can also handle both formats.

*** POTENTIAL INCOMPATIBILITY ***

Fix issues reported by dialyzer.

Miscellaneous updates

Own Id: OTP-8976

Type specs have been added/cleaned up. (Thanks to Kostis Sagonas.)

Own Id: OTP-8757

Warnings due to new autoimported BIFs removed

Own Id: OTP-8674 Aux Id: OTP-8579

The predefined builtin type tid() has been removed. Instead, ets:tid() should be used.

*** POTENTIAL INCOMPATIBILITY ***

Bugs have been fixed in the evaluation of comprehensions and short-circuit expressions in guards.

Own Id: OTP-8310

Miscellaneous corrections of the WX version of the debugger.

Own Id: OTP-8346

The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the frames are removed.

Own Id: OTP-8201

Added a new gui, start with debugger:start(gs) for old gui.

Own Id: OTP-7366

The undocumented, unsupported, and deprecated guard BIF is_constant/1 has been removed.

*** INCOMPATIBILITY with R12B ***

Own Id: OTP-7673

There is now experimental support for loading of code from archive files. See the documentation of code, init, erl_prim_loader and escript for more info.

The error handling of escripts has been improved.

An escript may now set explicit arguments to the emulator, such as -smp enabled.

An escript may now contain a precompiled beam file.

An escript may now contain an archive file containing one or more applications (experimental).

The internal module code_aux has been removed.

Own Id: OTP-7548 Aux Id: otp-6622

Minor changes.

Own Id: OTP-7388

The documentation has been updated so as to reflect the last updates of the Erlang shell as well as the minor modifications of the control sequence p of the io_lib module.

Superfluous empty lines have been removed from code examples and from Erlang shell examples.

Own Id: OTP-6944 Aux Id: OTP-6554, OTP-6911

Minor Makefile changes.

Own Id: OTP-6689

Obsolete guard tests (such as list()) have been replaced with the modern guard tests (such as is_list()).

Own Id: OTP-6725

Removed some dead code from dbg_ieval.

Own Id: OTP-6552

The interpreter could not handle the case where an expression that should evaluate to a fun referred to uninterpreted code.

Own Id: OTP-6061 Aux Id: seq10295

Timeout for gen_server calls within Debugger is now set to infinity.

Own Id: OTP-6103

Notification windows are now centered over a parent window.

Own Id: OTP-6011 Aux Id: OTP-5987

When interpreting a module, it is now checked that the module does not belong to the Kernel, STDLIB, GS or Debugger application, as interpreting a module used by the debugger/interpreter itself will lead to a deadlock or emulator crash.

Also int:interpretable(Mod) has been extended to return {error,{app,App}} if Mod belongs to one of the above applications.

Own Id: OTP-6020

andalso/orelse is now supported.

Own Id: OTP-6021 Aux Id: OTP-5894

When evaluating a guard expression for a fun function clause, the environment variable bindings were not taken into account.

Own Id: OTP-5837

A number of smaller improvements to the GUI:

Debugger can now handle try-catch. This meant large parts of the interpreter had to be rewritten. Also, some small changes to the GUI have been made.

Own Id: OTP-5730

It is now possible to encrypt the debug information in Beam files, to help keep the source code secret. See the documentation for compile on how to provide the key for encrypting, and the documentation for beam_lib on how to provide the key for decryption so that tools such as the Debugger, Xref, or Cover can be used.

The beam_lib:chunks/2 functions now accepts an additional chunk type 'compile_info' to retrieve the compilation information directly as a term. (Thanks to Tobias Lindahl.)

Own Id: OTP-5460 Aux Id: seq9787

The graphic applications now search for HTML documentation in the correct place.

Own Id: OTP-5381

Package support has been added to the debugger. Thanks to Richard Carlsson in the HiPE project.
